ETC-42 Introduction● What is it?

● Don't we have enough of them already?

● ETC-42 is a generic ETC

Not designed for a specific instrument

Very flexible calculation of the SNR

Easily extensible to reach any requirements

Targets a broader range of users

Simulation Results

Simulation is executed Simulation is executed by pressing the Execute by pressing the Execute button. Results of button. Results of multiple simulations are multiple simulations are shown in different tabs shown in different tabs for easy comparison. for easy comparison. The amount of visible The amount of visible results is controlled results is controlled from the Options menu.from the Options menu.



Simulation Results

Results can be viewed Results can be viewed in the graphics panelin the graphics panelor be broadcasted via or be broadcasted via SAMP as a VOTable SAMP as a VOTable



Graphics Panel

The Graphics panel is The Graphics panel is based on the JfreeChart based on the JfreeChart library and it provides all library and it provides all the default functionality the default functionality (zoom, line styles, etc)(zoom, line styles, etc)

It has been extended to It has been extended to support over-plotting by support over-plotting by drag and drop of the tabsdrag and drop of the tabs



Command Line Mode

The command line mode provides The command line mode provides several commands for setting the several commands for setting the input configurationinput configuration

The command “sh” can be used to The command “sh” can be used to execute native terminal commandsexecute native terminal commands



Command Line Mode

The “calculate” command runs the simulation The “calculate” command runs the simulation and saves the results in ASCII files. Results of and saves the results in ASCII files. Results of multiple simulations can be distinguished by multiple simulations can be distinguished by using the “outprefix” command.using the “outprefix” command.

Commands can be executed from a file as a Commands can be executed from a file as a script, using the “script” commandscript, using the “script” command



Plugin Framework

To easily extend the ETC-42 To easily extend the ETC-42 a plugin framework is a plugin framework is provided. Each plugin has provided. Each plugin has its own window and it can: its own window and it can: - access and modify the - access and modify the input configurationinput configuration - run the simulation (one- run the simulation (one or multiple times) and or multiple times) and retrieve the resultsretrieve the results - use the ETC-42 results - use the ETC-42 results panel for presentingpanel for presenting extra resultsextra results



Plugin example

● Writing plugins is simple!



Demo highlights

● Import / Export of the query configuration

● Flexible calculation framework supporting smart caching

● GUI or command line mode, supporting script execution

● SAMP enabled

● Plugin framework



Coming soon

● PSF calculation from image and data cube

● Adaptive Optics support

● Integral Field spectroscopy

● Simulated image as output

● Hybrid mode (GUI with command line)

● many more (suggestions are welcome)...
